Front Driveshaft Boot?

Will my Jeep spontaneously combust if I remove the boot from the front driveshaft slip-joint?

I ask because the band/clamp is *barely* rubbing against the exhaust cross-over pipe.

I know the rear driveshaft doesn't have a boot. And none of the older Jeeps have a boot on either shaft. So I'm not sure if the TJ front shaft specifically needs it, or the engineers just added it for giggles.

I've been running without a boot on mine for a while now. Had to replace the u-joints not too long ago, and the slip joint looked fine when I pulled it apart to inspect and regrease it.

I would never run without a boot. That boot is there not only to keep grease in BUT to keep dirt and grime out . You can damaged the Teflon coating or even the splines if it gets dirt and crap in there. IMO I would get it fixed. Its like $10-20 at a driveline shop ...just make sure if you take it off you mark where the splines were lined up before you slip it out to put new boot on..

You could loosen the down tube of the exhaust and push up and re-tighten.. There is a good bit of play in it. Its just a ball and socket connection.

Or clean the inside of the boot real well and glue it to the shaft and remove the clamp.... Leaving it better than taking off..
Dirt and sand gets in the splines it could lock up or fail to extend or collapse and crack your T case.

I've always been under the impression that the shafts built without a boot have instead some sort of a cap/seal at the splines to keep out dirt. I think at builders like TW it is an option you pick as to which way you go. That would explain shafts you see without boots. Removing boot though when shaft doesn't have that cap does not seem like a good plan to me.

My stock front driveshaft, obviously, came with the boot. However, there is a flexible seal on the splines, just like on my Tatton's rear driveshaft that came without a boot.

If it came with a boot, keep the boot... IMO

So... In the interest of full disclosure and accuracy, I figured out I had confused myself, and I never removed the boot from my front driveshaft. Please disregard everything I wrote above, and listen to the other responses.

For future reference, a shock boot works fine. You may have to trim the ends due to the smaller I.D.

You may think so at first, but, in particular on the front, driveshaft boots can be exposed to a decent amount of heat from exhaust piping. Driveshaft boots are made out of a material that is designed to handle that heat. Shock boots are not and will melt fairly easily.

I haven't had a problem with the close proximity on the rear shock:

Yet...

I'd guess there is a pretty good temp difference between the exhaust pipe that far back versus the down pipes coming off the manifold where the boot on the front driveshaft is in close proximity.

Well, The driveshaft boot on my tom wood's drive shaft was **** within a few months. The shock boot i put on there as been working much better since.
